Stridulation. 



This species produces a very noticeable stridulatioii, when- 

 ever disturbed. By holding the insect between the fingers, we 

 are able to observe that the sound is produced by rubbing the 

 caudal border of the pronotuni over the mesonotuni. The strid- 

 ulation can be made by working these parts togerlicr with the 

 fingers. 



Disagreeable Odor. 



N^one of our roaches are more disagreeable to handle. While 

 most roaches emit a liquid fecal matter, when disturbed, I have 

 never "found a species before that compares w'ith this for the 

 unpleasant odor, 



Rhy parobia ynaderae feeds extensively upon insect remains. 

 This is especially true with the nym])hs, which eat up their own 

 cast skins as fast as they shed llicni. I have not found them 

 eating each other, but they soon cIcmu up the I'cmains of any 

 soft-bodied insects that [ place in tli(> jars; a large dragon-fly 

 will be eaten over-night. 



The period of development of this species is evidently some- 

 wdiat longer than that of L. SHnnainensis; nymj^hs at 4 months 

 are less than one-fourth the size of the adidts. 



Phyllodroinia hospcs I'erk. 



IIAB, TTnder stones, nil)bish, etc; out of doors, also in 

 houses. 



The females of this species are wingless, I found them in 

 great numbers on the Waialae beach, beyond Diamond Head, 

 among camp refuse. They were associated with Nauphoeta hi- 

 rllala, Pliyllodromia hicrcxjlypliica and Eleufheroda dytiscoides. 

 One specimen of RJiyparohid Diadcrae nymph, was also found 

 in this place. Sevei-al of the females were found with the oothe- 

 cae still attached to them. On May 4th, 1914, one of these re- 

 producing females and a male were placed in a jar in the labora- 

 tory where observations were made on the reproductive habits 

 as indicated below :
